Have you ever heard the old saying "we only hurt the ones we love"? Many people are resistant to change even if they are part of the decision making process. I am sure that if the social worker has assured you that your aunt is doing well and making friends that she is. My suggestion would be that if she is shutting you out or being extremely rude that you take some time away to let her adjust to her new surroundings. Most likely what will happen is that she will start to miss you and realize all of the wonderful things that you do to help her.

 
You can always call the facility to see how she is doing without her knowing that you are checking up on her. I am sure that your aunt was a very independent person and is having a difficult time having to depend on others for assistance. She will also probably hold all her complaints for you as well. Often family members will try to make you feel guilty about your decision to place them into a facility. You may realize that this is what is best for her, but she may have unrealistic expectations. When living alone, seniors tend to become isolated and withdrawn. When they are around peers they become more active and tend to have less health complaints. When the brain is actively stimulated with activities it has a positive effect on our memory.

 
Give your aunt some time to adjust. Encourage her to seek out the social worker if she has concerns at the facility. This will give you an opportunity to have a pleasant visit. Plan something fun such as going out for lunch. Remember to take some time to care for yourself as well. Don't forget the social worker at the facility has experience in this area and he/she can be a great resource.
